This is great, it could be paired with buttons in the restrooms too. The hardware is essentially an iBeacon right? i.e. the person before me threw up, come please clean the washroom. Turning off WiFi and blueooth in bars is common though, it's the time of the evening that your battery is running low.

Love this shit! Need more time to develop tech. Could be used in other segments.

notify bartender and the person when he's locked in the washroom for a period of time
